Eating more protein automatically results in gaining more muscle mass.
Is it true that eating more protein automatically results in gaining more muscle mass?
No. Simply eating more protein does not automatically result in gaining muscle mass. Muscle hypertrophy requires appropriate mechanical stimuli, such as resistance training, rather than passive nutritional intake alone.
Verdict: REFUTED · 0 sources for, 2 against · Last checked
The claim states that eating more protein 'automatically' results in gaining muscle mass. While adequate dietary protein supports muscle health and can be necessary for hypertrophy, it does not automatically drive muscle growth without a proper stimulus like resistance training, and studies show that adding protein beyond adequate baselines yields no further hypertrophic benefit. Therefore, the claim is refuted.
